This is an AAO appeal decision — a case denied once and appealed. It shows how the framework is applied; it is not the filing population.
The Petitioner, a PhD student in nutrition science, proposed to continue researching the effects of seaweed consumption on gut microbiota to develop dietary interventions for obesity, later adding claims of using machine learning and AI to study the interactions between seaweed components, microbiota, and metabolism.

EB-2 threshold — addressed
Director found, and AAO agreed, Petitioner qualifies for EB-2 as advanced degree professional based on her U.S. master's degree in project management.
Prong 1 — national importancenot established · dispositive
“the record does not include sufficient information or supporting evidence to establish the national importance of her proposed endeavor and its prospective impact.”
“the letters do not sufficiently explain how her research will impact the field of nutrition science or matters of national or global importance more broadly.”
“many of the letters are from professors in the department where the Petitioner is pursuing her graduate studies, and while they describe her work in glowing terms, they do not provide enough detail to understand her endeavor's national importance.”
“this statement does not conform with the fact that the Petitioner's published materials have been infrequently cited, and no information is provided to explain the contradiction.”
“the Petitioner's proposed endeavor does not encompass a significant enough space in any of these fields to be considered of national importance.”
“because none of the documents discuss the Petitioner's research or her proposed endeavor, the information does not establish its national importance through any asserted or cognizable positive economic effects”

Where this case turned
- Citations insufficient · p1 — citation counts without qualitative account of impact
- Economic claims unsupported · p1 — job/revenue projections with no corroborating basis
- Letters conclusory · p1 — letters praise skills in general terms without tracing specific impact
- Letters not independent · p1 — letters come from employers and close collaborators, not independent experts
- Local, not national scope · p1 — impact confined to clients / a region
Notable
AAO noted several ancillary issues without deeming them dispositive: (1) some reference letter signatures did not conform to USCIS's signature policy prohibiting typewriter/auto-pen/stamp signatures, flagged 'for purposes of any future petition'; (2) the Petitioner's RFE response introduced new claims about AI/machine learning not mentioned in her initial statement, which the AAO suggested could implicate Matter of Izummi's prohibition on material changes to conform to USCIS requirements; (3) AAO independently verified citation counts via Google Scholar to contradict a support letter's claim of international circulation of her work.

What this case teaches
Analyst reading of the decision text.
Support letters and general context evidence (World Bank, NIFA, news articles) never tied the petitioner's specific seaweed/microbiota research to any nationally significant impact, only to field-general importance.
Obtain expert letters that explicitly connect the petitioner's specific research findings—not just the field's general importance—to concrete, evidenced national or global impact.
